Partially embedding of the quantum mechanical analog of the nonlinear sigma model
R. Amorim, J. Barcelos-Neto, C. Wotzasek
We consider the quantum mechanical analog of the nonlinear sigma model. There are difficulties to completely embed this theory by directly using the Batalin, Fradkin, Fradkina, and…
On the BFFT quantization of first order systems
Ricardo Amorim, Ronaldo Thibes
By using the field-antifield formalism, we show that the method of Batalin, Fradkin, Fradkina and Tyutin to convert Hamiltonian systems submitted to second class constraints introd…
Extended supersymmetry in D=1+1
R. Amorim, J. Barcelos-Neto
We extend superspace by introducing an antisymmetric tensorial coordinate. The resulting theory presents a supersymmetry with central charge. After integrating over the tensorial c…
Functional versus canonical quantization of a nonlocal massive vector-gauge theory
R. Amorim, J. Barcelos-Neto
It has been shown in literature that a possible mechanism of mass generation for gauge fields is through a topological coupling of vector and tensor fields. After integrating over…
